Thad: I think with Backgammon, the 2 schools of thought are pretty equal on this site. I have heard just as many people say they hate when someone resigns, because it takes away their "joy" at clearing their pieces off the board, as those who see no point in continuing a game that the outcome is already known.

Personally either way is fine with me. If it is a clear loss for myself, I will usually ask if my opponent minds if I resign.
